Mitsubishi 4M40 2.8L Turbo Diesel Cylinder Heads & Engine Parts

Looking for a premium aftermarket replacement Mitsubishi 4M40 2.8L turbo diesel cylinder head? We supply brand-new complete heads, gasket sets, and internal engine components from premium Australian stock with rapid nationwide delivery.

The Mitsubishi 4M40 2.8L engine (Triton, Pajero, Delica) is a legendary older power plant, but it is highly prone to pre-combustion chamber cracking and head warpage if the cooling system undergoes stress. Common symptoms of a failed 4M40 head include hard cold starts, excessive cooling system pressure, or oil mixing with the coolant.

Why Choose Midland Cylinder Heads?

  • Australian-Assembled Quality: Our licensed technicians build and inspect every brand-new cylinder head to strict OEM specifications, with all valve depths pre-set during assembly.
  • Thickest Composite Gaskets: Our kits feature premium, thick-grade composite head gaskets engineered to handle thermal expansion, ensure maximum clearance, and provide a perfect compression seal.
  • Included Torque Specs: Every order includes the correct tightening sequence and torque specifications for a perfect installation.
  • 12-Month Warranty: Drive with peace of mind with our 12-month, unlimited-kilometre warranty on all parts.
  • Fast Dispatch & No Core Exchange: Units are sold completely outright (no need to send your old head back) with fast dispatch from our Perth and Melbourne hubs.
